Computerized methods and interactive input systems for manipulation of 3D objects are disclosed. An image of 3D object is displayed on a 2D interactive surface, and input is received and is interpreted for manipulating the 3D object. When the 3D object is selected, rotation control handles indicating available rotation directions are displayed. In one embodiment, the method comprises capturing images of a 3D input space, recognizing at least one object in the images, and comparing the recognized objects in the images to determine a difference therebetween based on a difference threshold. Depending on the outcome of the comparison, the recognized objects are emerged and associated with digital content, or only one of the recognized objects is maintained and associated with digital content.

A computerized method of recognizing an input hand-drawn table formed by freeform line objects comprises transforming each freeform line object of the table into one of a vertical line segment and a horizontal line segment, generating a grid system based on the vertical and horizontal line segments and converting the generated grid system into a table object.
